多层螺旋CT灌注成像在胰腺疾病诊断中的应用
Diagnosis application of pancreatic disease with multi- slice spiral CT perfasion imaging
摘要
灌注是指血流通过毛细血管网将携带的氧和营养物质输送给组织细胞的过程,在一定程度上能反映器官、组织的血流动力学状态和功能情况。灌注成像(perfusion imaging)是指通过影像学手段来直观显示活体组织的灌注情况并作定量分析的方法。CT灌注成像具有扫描时间短、空间分辨力高、技术简单易行的特点,在显示血流动力学改变的同时能够提供清晰的断面解剖图像,特别是多层螺旋CT(multi—slice spiralCT,MSCT)的广泛应用,使CT灌注成像显示出了较高的临床应用价值。
